Hey, {{first_name | Founder}}!
Paid ads test funnels more than they test demand.
If you train the machine to optimize for the wrong goal, it will get very good at finding people who do the wrong thing.
Clicks are easy to buy. Cheap leads are easy to buy.
None of those prove that someone wants the product.
This is where founders burn money and still feel productive. The dashboard improves, the cost per event goes down, the campaign looks less embarrassing, and somehow the business is no closer to a customer.
Because the ad platform did exactly what you asked.
It found more of the people who click, browse, fill a form, or book a call because the offer sounded mildly interesting. It did not find more buyers. You never asked it to.
Until you do the boring and annoying part, pick the right goal, you are not learning. You are burning cash and calling it data.
A simple pre-launch test for ads:
"If a stranger does this, I will believe demand is real."
Not "visits the page."
Not "downloads the lead magnet."
Not "starts the quiz."
Pick the buyer action that would actually change your mind.
For a zero-customer startup, that is always an actual sale. If you can't, for some weirdly complicated reason do sale, do the closest funnel step to sale you can do. But remember: if the goal is not sales, you're not teaching ads to find you sales.
If the event is too rare to optimize, good. Means it's too early for paid ads. Go get the sales organically and manually first.
Paid ads can help you learn faster. But only after you define what learning would look like.
